Everywhere in the world women live longer than men - but this was not always the case. The available data from rich countries shows that women didn't live longer than men in the 19th century. Why do women live so longer than men in the present and how have these advantages gotten bigger in the past? The evidence is sketchy and we have only limited answers. While we are aware that there are behavioral, biological as well as environmental factors which play a significant role in the longevity of women over men, we do not know how much each factor contributes.

It is known that women live longer than men, زيوت تطويل الشعر regardless of weight. But it is not due to the fact that certain biological factors have changed. What are the factors that are changing? Some are well known and relatively straightforward, like the fact that men smoke more often. Some are more complex. For example, there is evidence that in rich countries the female advantage increased in part because infectious diseases used to affect women disproportionately a century ago, so advances in medicine that reduced the long-term health burden from infectious diseases, especially for survivors, ended up raising women's longevity disproportionately.

Everywhere in the world women tend to live longer than men
The first chart below shows life expectancy at birth for men and women. As we can see, every country is above the diagonal parity line , which means that in every country baby girls can expect to live longer than a newborn boy.1

Interestingly, this chart shows that although the female advantage is present everywhere, global differences are significant. In Russia women live 10 years longer than men, while in Bhutan the gap is just half an hour.

In wealthy countries, the advantage of women in longevity was smaller
Let's now look at how the female advantage in longevity has changed over time. The next chart plots male and female life expectancies when they were born in the US from 1790 to 2014. Two things stand out.

First, there is an upward trend. Men and women in America have longer lives than they were 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The second is that there is a widening gap: The female advantage in life expectancy used be very small but it increased substantially over the course of the last century.

By selecting 'Change Country from the chart, you are able to determine if these two points are applicable to other countries with available data: Sweden, France and the UK.
